Layer transition strategy in PCB Design - Dashboard Guide

Dashboard Mode - Layer transition strategy

Goal

Understand how to analyze and visualize the effectiveness of different layer transition strategies in PCB design to improve signal integrity and manufacturing efficiency.

Sample Data

Strategy	Number of Transitions	Signal Integrity Score	Manufacturing Cost ($)	Defect Rate (%)
Via Stitching	15	85	1200	2.5
Blind/Buried Vias	10	90	1500	1.8
Microvias	20	92	1800	1.2
Through-Hole Vias	25	75	1000	3.0
Backdrilling	12	88	1400	2.0

Dashboard Components

• KPI Card: Average Signal Integrity
  Formula: AVERAGE('Signal Integrity Score')
  Result: 86
• KPI Card: Average Manufacturing Cost
  Formula: AVERAGE('Manufacturing Cost ($)')
  Result: 1380
• Bar Chart: Number of Transitions by Strategy
  X-axis: Strategy
  Y-axis: Number of Transitions
  Shows how many layer transitions each strategy uses.
• Line Chart: Signal Integrity vs Manufacturing Cost
  X-axis: Manufacturing Cost ($)
  Y-axis: Signal Integrity Score
  Each point represents a strategy, showing trade-offs.
• Table: Defect Rate by Strategy
  Columns: Strategy, Defect Rate (%)
  Shows defect rates to identify quality issues.

Interactivity

A filter dropdown allows selection of one or multiple layer transition strategies. Selecting strategies updates all components to show data only for those strategies. For example, choosing 'Microvias' and 'Blind/Buried Vias' updates KPIs, charts, and table to reflect only those strategies.

Self Check

If you add a filter to select only strategies with a Defect Rate below 2%, which strategies remain and how do the KPIs update?

Answer: Strategies 'Blind/Buried Vias' (1.8%) and 'Microvias' (1.2%) remain. The Average Signal Integrity KPI updates to 91 (average of 90 and 92). The Average Manufacturing Cost KPI updates to 1650 (average of 1500 and 1800). The charts and table update accordingly to show only these two strategies.
